The way forwardState Planning Policy 2017 identifies local government as

the lead agency to utilise integrated evidence based

processes to join with the community and plan for local

circumstances.

• Slow onset risk• Defend/ adapt/ retreat• Context specific responses• The role of business and the Community• Cost benefit analysis • Integrated, multi disciplinary responses• Cost sharing arrangements for infrastructure costs• Inter-governmental collaboration• Dedicated delivery authority• Additional legislative powers, including compulsory

acquisition• Adaptation planning obligation• Balancing disparate investor interests
